To all, I am using squid-2.5STABLE4 with fully functioning LDAP talking to an active directory. This gives me a complete control of who is in what group and what is even better that the windows guys can actually drop people into the groups without any bother of the UNIX guys. Recently I have found that users are having problems with authenticating to sharepoint sites on different servers. Initially I suspected our firewall but it is actually this version of squid. Has this problem been rectified in a new squid versions. Shortly I will be building new production squid and would like this to be functioning.
